Hello John,

You’re already mentally on the beach or breathing some fresh mountain air – and these pictures are all competing with the to-do list still in front of you. Passport? Check. Out-of-office message? Check. Handover completed? Check. Security, however, is often the last thing on people's minds before a holiday.

That's why this month's edition focuses on a simple question: What should you check before you log off? Alongside practical holiday security tips, we'll also look further ahead at one of the biggest shifts in cybersecurity: the transition to post-quantum cryptography.

✈️ 30-second security check: Ready to switch off?

A good handover means more than making sure nobody has to call you on day two of your holiday. It means knowing your files, projects, and accounts are protected, too. Before your out-of-office takes over completely, ask yourself:

bulletpoint Did colleagues covering for you have access only to the files they need?

bulletpoint Do shared links have an expiry date?

bulletpoint Are key project details, tasks, and decisions documented in one secure space?

If any of these made you pause, our latest holiday security checklist is worth a quick read:

⏳ The post-quantum cryptography countdown has started

How long does your data need to stay confidential? For many organizations, the answer is years (if not decades). Think intellectual property, contracts, or other business-critical data.

That’s why security experts are increasingly warning about "harvest now, decrypt later" risks. No, it's not cryptographic haiku. It's a strategy where attackers collect encrypted data today and store it for future decryption once quantum computers become mainstream (and unignorable).

The takeaway from Germany's Federal Office for Information Security (BSI) is clear: start preparing now. With 2031 set as a key milestone, organizations should begin the transition to hybrid, quantum-safe cryptography. Learn more about the latest BSI recommendations:

Protecting your data – from holiday handovers to the post-quantum era

Quick security checks before your holiday can help protect your data while you're away. But some security decisions need to last far longer than the summer. That’s why questions like “How is my data encrypted?” and “Is the provider preparing for the post-quantum transition?” are becoming increasingly relevant when choosing a cloud provider.
